Total thyroidectomy: Conventional Suture Ligation technique versus sutureless techniques using Harmonic Scalpel or Maxium

Improving Operating Room Efficiency in Otolaryngology-Head and Neck Surgery: A Scoping Review

OBJECTIVE

One minute of operating room (OR) time costs $36 to 37. However, ORs are notoriously inefficient. There is growing literature on improving OR efficiency, but no formal review of this topic within otolaryngology has been performed. This study reviews and synthesizes the current literature on improving OR efficiency within otolaryngology.

DATA SOURCES

MEDLINE, EMBASE, Web of Science, CINAHL, Cochrane Library, preprints.org, and medRxiv were searched on November 4, 2022.

REVIEW METHODS

Published English studies were included if they reported on metrics for improving OR efficiency within otolaryngology. There were no publication date restrictions. Articles were screened by 2 reviewers. Preferred Reporting Items for Systematic Reviews and Meta-analysis reporting for scoping reviews was followed.

RESULTS

The search yielded 9316 no-duplicate articles; 129 articles were included. Most of the studies reported on head and neck procedures (n = 52/129). The main tactics included surgical considerations: hemostatic devices, techniques, and team/simultaneous approaches; anesthetic considerations: local anesthetic and laryngeal mask airways; procedure location considerations: procedures outside of the OR and remote technologies; standardization: equipment, checklists, and personnel; scheduling considerations: use of machine learning for booking, considering patient/surgeon factors, and utilizing dedicated OR time/multidisciplinary teams for on-call cases.

CONCLUSION

The current literature brings to attention numerous strategies for improving OR efficiency within otolaryngology. Applying these strategies and implementing novel techniques to manage surgical cases may assist in offloading overloaded health care systems and improving access to care while facilitating patient safety and outcomes. Anticipated barriers to implementation include resistance to change, funding, and the current strain on health care systems and providers.

Outcome Analysis of Total Thyroidectomy: Conventional Suture Ligation Technique vs Sutureless Technique

INTRODUCTION

Total thyroidectomy is a common surgical procedure in endocrine surgery. However, it carries potential complications such as damage to the recurrent laryngeal nerve, permanent hypoparathyroidism, and bleeding.  Methods: A prospective study was conducted at the Professorial Surgical Unit, Jaffna Teaching Hospital, involving consecutive patients who underwent total thyroidectomy. Patients with certain conditions were excluded from the study. The data collected were analyzed using IBM SPSS Statistics for Windows, Version 25 (Released 2017; IBM Corp., Armonk, New York, United States).

RESULTS

This study included 59 patients who had total thyroidectomy from January 2018 to January 2021 at the Professorial Surgical Unit, Jaffna Teaching Hospital. Of these, 45 underwent conventional suture ligation (CSL), and 17 had a sutureless (SL) technique. Mean ages were 44±12.47 years (range: 23 to 68) for CSL and 47.63±13.37 years (range: 27 to 73) for SL. Operative time was 2.16 ± 0.32 hours for CSL and 1.56 ± 0.49 hours for SL. Intraoperative and postoperative bleeding occurred in 2.38% of CSL cases but not in SL. Postoperative hypocalcemia was 7.14% for CSL and 5.88% for SL. Postoperative stays averaged 3.83 ± 1.56 days for CSL and 3.41 ± 1.62 days for SL.

DISCUSSION

The study found that the operative time differed significantly between the suture and SL techniques. However, there was no statistically significant difference in postoperative drainage volume or postoperative complications.

CONCLUSION

The SL technique was shown to be superior to the conventional suture ligation technique for total thyroidectomy. It resulted in shorter operative time, reduced intraoperative bleeding, lower incidence of postoperative drainage, fewer postoperative voice changes, and shorter hospital stays. Therefore, the SL technique was deemed safe, efficient, and effective for total thyroidectomy compared to the conventional suture ligation technique.

High-energy devices in different surgical settings: lessons learnt from a full health technology assessment report developed by SICE (Società Italiana di Chirurgia Endoscopica)

BACKGROUND

The present paper aims at evaluating the potential benefits of high-energy devices (HEDs) in the Italian surgical practice, defining the comparative efficacy and safety profiles, as well as the potential economic and organizational advantages for hospitals and patients, with respect to standard monopolar or bipolar devices.

METHODS

A Health Technology Assessment was conducted in 2021 assuming the hospital perspective, comparing HEDs and standard monopolar/bipolar devices, within eleven surgical settings: appendectomy, hepatic resections, colorectal resections, cholecystectomy, splenectomy, hemorrhoidectomy, thyroidectomy, esophago-gastrectomy, breast surgery, adrenalectomy, and pancreatectomy. The nine EUnetHTA Core Model dimensions were deployed considering a multi-methods approach. Both qualitative and quantitative methods were used: (1) a systematic literature review for the definition of the comparative efficacy and safety data; (2) administration of qualitative questionnaires, completed by 23 healthcare professionals (according to 7-item Likert scale, ranging from - 3 to + 3); and (3) health-economics tools, useful for the economic evaluation of the clinical pathway and budget impact analysis, and for the definition of the organizational and accessibility advantages, in terms of time or procedures' savings.

RESULTS

The literature declared a decrease in operating time and length of stay in using HEDs in most surgical settings. While HEDs would lead to a marginal investment for the conduction of 178,619 surgeries on annual basis, their routinely implementation would generate significant organizational savings. A decrease equal to - 5.25/-9.02% of operating room time and to - 5.03/-30.73% of length of stay emerged. An advantage in accessibility to surgery could be hypothesized in a 9% of increase, due to the gaining in operatory slots. Professionals' perceptions crystallized and confirmed literature evidence, declaring a better safety and effectiveness profile. An improvement in both patients and caregivers' quality-of-life emerged.

CONCLUSIONS

The results have demonstrated the strategic relevance related to HEDs introduction, their economic sustainability, and feasibility, as well as the potentialities in process improvement.

Energy Based Vessel Sealing Devices in Thyroid Surgery: A Systematic Review to Clarify the Relationship with Recurrent Laryngeal Nerve Injuries

Background and objectives: The principal complications associated with thyroid surgery consist in postoperative recurrent laryngeal nerve (RLN) palsy, hypoparathyroidism, intra-operative and post-operative hemorrhage. In this paper, structured as a literature review, we describe the current knowledge and the technical improvements currently employed in the field of thyroid surgery, focusing on the contribution of energy based devices in relation with the reduction of the operating time and the odds of possible complication. Materials and methods: a relevant systematic literature search on Pubmed was carried out including works from 2004 through 2019, selecting studies providing information on the energy based devices employed in surgeries and statistic data concerning RNL (transient and permanent) injury and operative time. Results: Nineteen studies were reviewed, dealing with 4468 patients in total. The operative variables considered in this study are: employed device, number of patients, pathological conditions affecting the patients, surgical treatment, RNL injury percentage and the operating time, offering an insight on different patient conditions and their relative operative outcomes. A total of 1843 patients, accounting to the 41.2% of the total pool, underwent the traditional technique operation, while 2605 patients (58.3%) were treated employing the energy based devices techniques. Thyroidectomy performed by approaches different from traditional (for example robotic, MIVAT (Mini Invasive Video Assisted thyroidectomy)) were excluded from this study. Conclusions: The energy-based vessel sealing devices in study, represent a safe and efficient alternative to the traditional clamp-and-tie hand technique in the thyroidal surgery scenario, granting a reduction in operating time while not increasing RNL injury rates. According to this information, a preference for energy based devices techniques might be expressed, furthermore, a progressively higher usage rate for these devices is expected in the near future.

Plasma miR-323 as a Biomarker for Screening Papillary Thyroid Cancer From Healthy Controls

The present study aims to evaluate whether plasma miR-323 serves as a potential biomarker to screen patients with papillary thyroid cancer (PTC) from healthy controls. Real-time PCR was performed to evaluate miR-323 expression in healthy controls and benign thyroid nodule (BTN) and PTC patients. Receiver operating characteristic (ROC) curve analysis was used to evaluate whether plasma miR-323 could be used to screen PTC patients from BTN patients and healthy controls. Plasma miR-323 was significantly increased in PTC patients compared with that in BNT patients and healthy controls. Moreover, miR-323 in the thyroid tissue was significantly increased in PTC patients when compared to BNT patients. We further showed that plasma and tissue miR-323 levels were significantly increased in PTC patients with metastasis compared to those without metastasis. Plasma miR-323 was significantly increased in PTC patients with BRAF V600E mutation when compared to those with wild-type BRAF. Furthermore, plasma miR-323 was significantly increased in PTC patients with higher Tg-FNAB. ROC analysis showed that plasma miR-323 could distinguish PTC patients from BNT patients and healthy controls. The present study demonstrated that plasma miR-323 might be an effective noninvasive indicator for PTC progression and serve as a biomarker for the diagnosis of PTC.

Risk factors and effects of hypocalcemia prior to discharge following thyroidectomy

PURPOSE

To find patient and surgical characteristics associated with hypocalcemia prior to discharge (HPTD) in thyroidectomy patients.

MATERIALS AND METHODS

In a retrospective analysis of the 2016-2017 National Surgical Quality Improvement Program, eligible total thyroidectomy patients were stratified into cohorts based on development of HPTD. We identified demographic and surgical risk factors for the development of hypocalcemia via binary logistic regression and identified the negative sequelae of HPTD utilizing univariate and multivariate methods.

RESULTS

We identified a total of 6519 patients who underwent total thyroidectomy, of which 450 (6.9%) had HPTD. Predictors associated with an increased incidence of HPTD included female sex (OR: 1.737 [95% CI: 1.319-2.288]; p < .001), increased operative time (OR: 1.003 [1.002-1.004]; p < .001), and central neck dissection (OR: 1.484 [1.190-1.850]; p < .001). However, factors that decreased incidence of HPTD included increased age, obesity (OR: 0.648 [0.501-0.837]; p = .001), and the use of vessel sealant devices (VSD) (OR: 0.650 [0.527-0.803]; p < .001). Multivariate analysis further revealed that HPTD independently led to an increased hospitalization length after surgery (B: 0.708 [0.607-0.809]; p < .001) and an increased 30-day readmission rate (OR: 2.429 [1.594-3.704]; p < .001).

CONCLUSION

Obesity, increased age, and intra-operative VSD use were significantly associated with decreased rates of HPTD after total thyroidectomy. Female sex, longer operations, and central neck dissections were associated with HPTD. Delineating risk factors and protective factors for HPTD in total thyroidectomy patients is important as patients with HPTD were found to be at a significantly higher risk for longer post-operative stays, increased odds of 30-day readmission, and increased hypocalcemia-related event.

Comparing Hematoma Incidence between Hemostatic Devices in Total Thyroidectomy: A Systematic Review and Meta-analysis

OBJECTIVE

Alternative energy devices have become a popular alternative to conventional hemostasis in thyroid surgery. These devices have been shown to reduce operative time and thermal nerve injury. As hemostasis is paramount in thyroid surgery, we sought to examine the relative efficacy of 2 alternate energy devices compared to conventional hemostasis in preventing postoperative hematoma following total thyroidectomy.

DATA SOURCES

Ovid MEDLINE, EMBASE, PubMed, and Cochrane Central Register of Controlled Trials.

REVIEW METHODS

A systematic literature search was performed for all relevant English-language studies published between 1946 and July 2018. Two authors independently extracted data and analyzed articles for quality using the National Institute of Health Quality Assessment Scale. Our primary outcome of interest was hematoma requiring reoperation.

RESULTS

A total of 348 studies were screened, with 23 meeting the inclusion criteria. We found no significant difference in postoperative hematoma rates using alternate energy devices compared to conventional hemostasis (P = .370, .317). Network meta-analysis echoed the results of conventional meta-analysis, demonstrating no significant difference in hematoma rates.

CONCLUSIONS

We found no significant difference in postoperative hematoma rates following total thyroidectomy for any indication with the use of alternate energy devices compared to conventional hemostatic techniques. This suggests that hematoma occurrence does not necessarily need to be considered when choosing between these hemostatic devices. This information may help guide surgeons' decisions regarding choice of hemostatic technique during thyroid surgery.

Safety of drainless excision of the submandibular gland

Introduction

Percutaneous drains can be associated with several complications, including infection, fistula formation, discomfort and prolonged hospitalization.

Objective

The aim of this study was to evaluate the safety of submandibular gland excision without the use of surgical drains.

Methods

We analyzed the surgery time, postoperative complications such as bleeding, facial palsy, seroma, and repeat exploration of wounds and duration of the hospital stay. Excision of the submandibular gland via a transcervical approach was undertaken by two surgeons. Prior to wound closure, the skin flap and wound bed were approximated using hemostatic fibrin glue (Greenplast-Q PFS KIT®, GC Greencross, Youngin, Korea). Neither saline irrigation nor insertion of a percutaneous drain were included.

Results

A total of 23 patients underwent submandibular gland excision. The study group consisted of 14 men (60.8%) and 9 women (39.2%) (mean age, 47.6 years; range, 24–70 years). There were two patients who had minor complications. One patient showed minor bleeding on the skin incision line immediately postoperatively, and one developed a seroma at 7 days postoperatively. There were no major surgical complications. Total duration of the surgery from skin incision to closure averaged 44.86 minutes. Mean duration of the hospital stay was 3.17 days. Patients were discharged on average at 1.17 days after surgery.

Conclusion

The submandibular gland can be safely excised without the use of a surgical drain, therefore allowing early patient discharge.

Comparison of surgical outcomes and complications between the Harmonic FOCUS and conventional surgery for open thyroidectomy

The aim of the present study was to evaluate the potential advantages of the ultrasonic scalpel compared with the conventional technique in thyroid surgery. Patients with resectable thyroid cancer and Basedow's disease were assigned to ultrasonic scalpel or conventional technique (knot-tying and electrocoagulation). The present study used the Harmonic FOCUS^® (HF) as an ultrasonic scalpel. Between February 2013 and May 2016, 45 patients were enrolled into the study. Duration of the surgery was significantly decreased in the HF group compared with the conventional surgery (CS) group (median 142 vs. 151 min; P=0.0406). Intraoperative blood loss and total volume of drainage fluid were significantly decreased in the HF group compared with the CS group (median 40 vs. 125 ml; P=0.0054, and median 120 vs. 175.5 ml; P=0.0490). Duration of drain placement and length of hospitalization stay were similar in the two groups. Furthermore, the overall incidence of postoperative complications did not differ between the two groups. Overall, the present study suggests that open thyroidectomy using the HF is safe and effective and not associated with any increase in complications.
